-- Make GL auto-posting an explicit per-company flag instead of inferring it from
-- the presence of non-acmacc journal entries. The old heuristic
-- (accounting.gl_managed = "no foreign/imported journal entries") broke the moment
-- a normal MANUAL journal entry (external_source null) was added to a managed
-- company — it silently flipped the company to "unmanaged" and disabled all GL
-- automation. Companies with a large imported GL are flagged off; platform-managed
-- companies default on.
